The door catch yieldedtheir wrestling, struggling weight drew it inward.But, Sandy clung obstinately to his theories, why did Jeff pick this haunted place and cut the ignitionand why was the door up in the first place?
Anyhow, they discovered the false emeralds and tried to destroy them. Sandy was more confident at Larrys acceptance of his ideas.
He went inside the hangar, closing the door, and resumed his vigil.
If a cutting movement were performed by the tool supports, it would necessarily follow that the larger a piece to be planed, and the greater the distance from the platen to the cutting point, the farther a tool must be from its supports; a reversal of the conditions required; because the heavier the work the greater the cutting strain will be, and the tool supports less able to withstand the strains to be resisted.
Theyre diving! cried Sandy.
Women and children had frequently been ill-treated in a most atrocious manner, aged and sick people were dragged out of the houses, and flung down in the street. This happened, for example, to an old man, who lay dying in his cellar. In spite of the supplications of his wife and two sons, he was flung on the cobbles, where he died soon. The sons were taken prisoners and sent away. His widow assists at present nursing other unfortunates at Professor Noyons' hospital.Inherent or cooling strains in castings is much more intricate than shrinkage: it is, in fact, one of the most uncertain and obscure matters that pattern-makers and moulders have to contend with. Inherent strains may weaken castings, or cause them to break while cooling, or sometimes even after they are finished; and in many kinds of works such strains must be carefully guarded against, both in the preparation of designs and the arrangement of patterns, especially for wheels and pulleys with spokes, and for struts or braces with both ends fixed. The main difficulty resulting from cooling strains, however, is that of castings being warped and sprung; this difficulty is continually present in the foundry and machine-shop, and there is perhaps no problem in the whole range of mechanical manipulation of which there exists more diversity of opinion and practice than of means to prevent the springing of castings. This being the case, an apprentice can hardly hope for much information here. There is no doubt of springing and strains in castings being the result of constant causes that might be fully understood if it were not for the ever-changing conditions which exist in casting, both as to the form of pieces, the temperature and quality of metal, mode of cooling, and so on.
